China sent coast guard vessels into waters east of Taiwan and claimed it was conducting routine law enforcement — a move Taipei calls harassment dressed up as policing, and a fresh sign of pressure on Taiwan.

• Two Chinese coast guard ships were operating east of Taiwan's outlying islands, with Beijing calling it a "regular law enforcement patrol."
• Taiwan's Coast Guard sent its own patrol ships and says it is tracking the vessels the whole time.
• Taipei rejects the claim outright, saying China has no jurisdiction over any waters around Taiwan.
• The language matters: Beijing's use of "China's Taiwan island" is part of a push to make its claims sound normal and legal.

Outlook: These patrols are likely to keep repeating, with each side restating its claim while ships shadow each other at sea.
